So yeah when I turn the key, the starter just turns freely, most of the time, turn it a couple times and it will engage or sometimes engage on the first turn, but it is gradually getting worse and let me tell you how frusterating it is to let the glow plugs warm their full cycle just to have it negated by the starter not kicking in. So is it the teeth on the starter or a dead spot on the ring gear. If it was the latter I would figure it would never engage.
If it is indeed the starter, can it be easily repaired without replacing the whole thing?
